Hi,
I want to change the datatype of an existing column from char to
varbinary. When I run the "Alter Table" statement, I get the
following error message -
Disallowed implicit conversion from data type char to data type
varbinary, table 'test.dbo.testalter', column 'col1'. Use the CONVERT
function to run this query.

Is there a way to use a column alias in an another calculation within the
same query? Since I am using some long and complex logic to compute total1
and total2, I don't want to repeat the same logic to compute the ratio of
those two columns. I know that I can do a nested query, but that seems too
lengthy as well since I actually have many, many columns.
select
total1 = sum(case(long complex logic)),
total2 = sum(case(another long...

Either I missed something, or ALTER TABLE does not have this
capability. Is there any way of doing it except
DROPping all constraints which mention this table,
EXPORTing the data,
DROPping the table,
reCREATEing the table without the 'NOT NULL property,
reCREATEing the INDEXes,
reloading the data,
redefining all of DROPped constraints
reCREATE the view which were marked inactive by the above.

I am trying to turn a short and fat (63 columns) table into one that is tall
and skinny (7 columns). Basically, I am trying to create a "reverse
crosstab" using a looping structure in VBA along with SQL. I'd like to take
the name of the column and input it into a descritor field.
This isn't the table, but will serve as a better illustration than the real
deal.
If the table looks like this:

Hi all,
I've just finished almost all of what has turned out to be a real bear of a
project. It has to import data from a monthly spreadsheet export from another
program, and convert that into normalized data. The task is made more
difficult by the fact that the structure itself can vary from month to month
(in well defined ways).
So, I used the SQL-centric approach, taking vertical stripes at a time so
that, for instance, for each...

Hi,
I am trying to move a datacolumn in a datatable. What I have tried so
far is to create a new datacolumn set it equal to the one I want to
remove and then remove it, add another column and add it back again in
the place I want it.
tableStyle.MappingName = "DVGlobalPrices";
System.Data.DataColumn dCol = new DataColumn();

I'm setting the column with for a gridview (25+- columns) and have
paging turned on.
When the gridview is first displayed, the column widths are all set to
the default. But after paging to another page, the widths are set as
they should be.
Going back to page one, the widths are still correct.
Not a clue what's going on here!

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
